Week 9 - Project 1 - Door Applique Design with Engineering Features

REPORT

ABSTRACT: This is a bit different from earlier challenges as this week ninth part is a project. In this project we need to design a door applique with its proper supporting and attachment body. In this project I also need to design some important supporting elements on the backside of the door applique body. The name of the other supporting elements is four way locator, two way locator and heat stakes.

INTRODUCTION: In this design project we need to develope every feature with proper rules and regulations. It is necessary as we need to provide a required amount of tolerance on about every developed feature. It is important to design and develope a required amount of tolerance as we need to make whole arresting of components smmoth. That is why in this project I developed two four-way locators and one two-way locators. After that on the left out space I developed the heat stakes at equal distance from each other.

The images of 4-way Locators is as:

A 2-way Locator is as:

And at last the images of heat stakes is as:

After developing the supporting and locating elements on the back side of the DOOR APPLIQUE body, The final structure of the door Applique body is looks like:

METHODOLOGY: The developement of features for proper connection during assembly is done in the initial phase. After that we need to develope a proper draft 0.5 degrees in every of the developed features in order to proceed smoothly in the injection moulding process. The injection moulding is done easily if there is a draft on the outer surface of the features and body.

After that in the continuation of the project we need to develope a required amount of tolerance for each and every features. We also nned to measure it as the maximum amount odf tolerance that is provided is 0.999. It should never be 1 or greater than 1.

The tolerance provided in supporting attachment body, the final layout is as:

RESULTS:

The final results for the door applique and door attachment is done in the form of draft analysis of whole structure. The whole body is will act as unioun or we can have multiple draft analysis for seperate bodies:

The draft analysis for DOOR AAPLIQUE BODY is:

The draft analysis of attachment is as:

The final result is as:
